 * Hi [@rvof](https://wordpress.org/support/users/rvof/),
 * Thank you for reporting this issue!
 * The warning **“Undefined array key ‘anylc_nonce’”** may be related to our new**
   opt-in usage tracking** feature. It appears when the usage-tracking request doesn’t
   receive the expected nonce value in the admin area. This is only a PHP notice
   and shouldn’t break your site, but we certainly want to clean it up.
 * To help us pinpoint the trigger, could you let us know what action you were performing
   when the message appeared (for example, dismissing the opt-in prompt or saving
   settings)?
 * We appreciate you bringing this to our attention

 * Hi [@muhammadwpfolio](https://wordpress.org/support/users/muhammadwpfolio/)
 * My installation is Windows, and even with the warnings disabled, the system crashes
   when the error is related to a plugin. Only by enabling log recording does it
   redirect to a file. Otherwise, the system crashes. No action is being taken, 
   only accessing the website or the administrative area.

 * Hi [@rvof](https://wordpress.org/support/users/rvof/),
 * Thank you for the additional details.
 * We’ve forwarded this to our development team so they can investigate and try 
   to reproduce the issue on a similar Windows/IIS environment.
 * To help us narrow it down, could you let us know:
    - Does the warning appear as soon as you load the admin dashboard, or only on
      specific pages?
    - Has anything else recently changed on the server (PHP version, caching, security
      tools, etc.)?
 * Any extra information will help our team diagnose the issue more quickly.

 * Recomendação de correção:
 * if (!isset($_POST[‘anylc_nonce’]) || empty($_POST[‘anylc_nonce’])) {
   wp_send_json_error(‘
   Nonce inválido’);return;}$nonce = sanitize_text_field($_POST[‘anylc_nonce’]);

 * Hi [@rvof](https://wordpress.org/support/users/rvof/),
 * Just a quick update, our development team has reviewed the issue, and the fix
   will be included in the next plugin release. Once the new version is available,
   you can simply update the plugin and the notice should be resolved.
 * In the meantime, your site will continue to work normally, so there’s no action
   needed on your side right now.
 * Thank you again for reporting this and for your patience.
